Abstract：
Based on the orthogonal test method, numerical simulation software was used to simulate the solidification process of the left box of aluminum alloy motorcycle engine. The results show that the injection velocity is faster, the time for the liquid metal to fill the cavity is shorter, the oxide inclusions are more less. The mold temperature is higher, the solidification time of liquid metal is longer and the grain size is larger. The four factors have similar influence on shrinkage cavity and porosity of casting and air pressure. Shrinkage cavity and porosity are mainly distributed in regions with large wall thickness around casting holes, and the air pressure distribution is relatively uniform.
